Rafael Espindola 419b6d7ce4 Make ARM and X86 LowerMEMCPY identical by moving the isThumb check into getMaxInlineSizeThreshold 
and by restructuring the X86 version.

New I just have to move this to a common place :-)

Rafael Espindola 063f177300 Make ARM an X86 memcpy expansion more similar to each other. 
Now both subtarget define getMaxInlineSizeThreshold and the expansion uses it.

This should not change generated code.

be copied from an object that already has an allocated buffer.

Evan Cheng c2dbfee43f It's not safe to tell SplitCriticalEdge to merge identical edges. It may delete the phi instruction that's being processed.

Ted Kremenek 4c0ef37fbb Refactored CFG construction code that processes DeclStmts to use StmtIterator. 
Now CFG construction transparently supports Variable Length Array declarations
with expressions for their sizes, and typedefs that include VLAs.

Ted Kremenek c08bca6ae8 Removed SrcMgr::FileInfo and SrcMgr::InfoRec and replaced them with a 
single class: ContentCache.  This simplifies the logic in
SourceManager and makes the ownership of MemoryBuffers clearer.

Ted Kremenek 9139310c76 Added vector to ASTContext to store references to "complete" VLA types 
(VLAs with a specified size expresssion).  This vector owns the
references to these type objects.

llvm-svn: 43500

Duncan Sands 9ad5465005 Add support for expanding trunc stores. Consider 
storing an i170 on a 32 bit machine.  This is first
promoted to a trunc-i170 store of an i256.  On a
little-endian machine this expands to a store of
an i128 and a trunc-i42 store of an i128.  The
trunc-i42 store is further expanded to a trunc-i42
store of an i64, then to a store of an i32 and a
trunc-i10 store of an i32.  At this point the operand
type is legal (i32) and expansion stops (legalization
of the trunc-i10 needs to be handled in LegalizeDAG.cpp).
On big-endian machines the high bits are stored first,
and some bit-fiddling is needed in order to generate
aligned stores.
